I tried calculating the Index of Hydrogen Deficiency for C6H15SiCl, and I get negative one. I get this value by subtracting the number of chlorine and hydrogen atoms from that of the carbon atoms, and then adding one. I don't think I am supposed to do anything with the number of silicon atoms. Is this correct/normal?

    $\begingroup$ SiH4 has the same IHD as CH4, so Si should be treated as C. chem.libretexts.org/Bookshelves/Organic_Chemistry/… Always think thoroughly about possible answers to your question and search for them before asking. $\endgroup$

  • $\begingroup$ In case of doubts, analy, how is hydrogen deficiency changed, if H- of -CH2- are replaced by other atoms or their groups. $\endgroup$
